Figure 4: ROS generation measured by H2DCFDA. As expected, treatmentwith hydrogen peroxide resulted in greater ROS generation. Treatment withnorepinephrine resulted in significantly less ROS generation than in untreatedcells (p<0.01). Norepinephrine treatment after hydrogen peroxide treatmentresulted in decreased ROS generation, however this different was notsignificant (p=0.14). H2O2: Hydrogen Peroxide; NE: Norepinephrine.
